Question 1

A customer has the following requirements for their VDI deployment:

Which EMC technologies should be recommended?

AXtremIO, RecoverPoint CRR, and VPLEX only

BVSPEX Blue, RecoverPoint CDP, and VNX

CIsilon, VSPEX Blue, VPLEX, and RecoverPoint CDP

DXtremIO, RecoverPoint CRR, VPLEX, and Isilon

Correct answer: A

The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in-time data recovery and a new 'snap and replicate' mechanism for local and remote replication (XRP).

Splitter-based replication, using VPLEX

RecoverPoint splitter-based replication provides synchronous replication, continuous replication with fine recovery granularity (journal based), and replication for active-active datacenters.

Question 2

A storage administrator is adding both an XtremIO and third-party storage arrays to their existing infrastructure. The administrator is using ViPR SRM to monitor the environment.

Which requirement is needed to implement this solution?

AA single third-party Solution Pack is required to manage both storage arrays

BEach storage needs its own Solution Pack

CEach storage array requires two Solution Packs; one for monitoring and one for performance

DA single XtremIO Solution Pack is required to manage both storage arrays

Correct answer: B

Question 3

A customer is considering a six brick dispersed cluster using 340U racks. The customer wants advice on racking the InfiniBand switches.

Which recommendation should be provided?

AInstall the InfiniBand switches in Rack 1 with a 1U placeholder between the switches.

BInstall an InfiniBand switch in Racks 1 and 3 with a 1U placeholder between the X-Bricks.

CInstall the InfiniBand switches in Rack 2 with a 1U placeholder between the switches.

DInstall the InfiniBand switches in Rack 3 with a 2U placeholder between the switches

Correct answer: B

Question 4

How can REST API commands be run to manage and monitor an XtremIO cluster?

AFrom the REST API CLI built into each X-Brick

BFrom the REST API GUI built into each X-Brick

CFrom a third-party GUI

DFrom the REST API tab in the XMS GUI

Correct answer: C

The XtremIO's RESTful API allows HTTPS-based interface for automation, orchestration, query and provisioning of the system. With the API, third party applications can be used to control and fully administer the array.

Normally you would access the API using some form of programming/scripting language, such as Python or Perl. However for the purposes of learning or testing concepts there are a number of tools that work better, such as HTTPRrequester and curl.

* Curl is a command-line tool that exists in all Linux distributions, and is available for most other Unix OSes as well as Windows.

To use curl to access XtremIO you'll need to pass it a few options, such as the username/password to access the array (any valid account on the XtremIO XMS will work), the URL of the API, and potentially a few options such as -k to tell curl not to validate the SSL certificate (presuming you don't have a valid certificate installed), and -s (silent) to stop curl displaying it's progress as it downloads the response.

* HTTPRequester is a browser extension that is available for both Chrome and Firefox.

As with for curl, you'll need to provide a username/password, which is done by clicking on the ''Authentication...'' box, which adds two boxes below the URL for the username and the password.

Question 5

A customer has a requirement to replicate their VDI to a newly purchased data center located 5 miles away. They require 10-day retention at each site and a continuous replication RPO. However, they want to have the same storage platform at each site. They have a limited budget but need to meet their requirements.

Which solution should be recommended to the customer?

AXtremIO and OpenStack

BXtremIO with VPLEX and RecoverPoint

CXtremIO and RecoverPoint

DXtremIO and MirrorView/A replication

Correct answer: C

The EMC RecoverPoint family provides cost-effective, local continuous data protection (CDP), continuous remote replication (CRR), and continuous local and remote replication (CLR) that allows for any-point-in-time data recovery and a new 'snap and replicate' mechanism for local and remote replication (XRP).

Native replication support for XtremIO

The native replication support for XtremIO is designed for high-performance and low-latency applications that provides a low Recovery Point Objective of one minute or less and immediate RTO.
